AKKUTEC 2424P

 

Short description

The battery buffered DC power supply is working according to the stand-by parallel mode and ensures in connection with a lead-acid accumulator a safe continuous DC power supply during a determined time interval in case of mains failure. The total output current is shared between supply of the loads and charging of the batteries.

The power supply is characterized by the follow

ing properties:

  • Primary switched power supply with I/U charging characteristic
  • Active power factor correction (PFC)
  • Micro-controller supported lead accumulator management
  • RS232 for monitoring and parameterization
  • Temperature tracking of the charging voltage with external temperature sensor
